Fail to Update Firmware in Windows 7

I tried in Windows 7 and Windows 8 environment but still not able to update the firmware for my new purchased V6 and RF60. I also tried 3 different USB cable and still got the No device connected. I can see the them under device manage and Other Devices. Any idea how I can get them connect and recognized by my computer please?

Yes, I followed the instruction and hold the menu button and turn to TX or RX model already. Also, I tried on 5 differnt computers Windows 7 and 8. Nono of them can detect V6 and RF60. I also tried a few different mini usb cable. And idea how to solve this please?

are you pressing the menu key and keeping it pressed while turning on the V6 in preparation for the firmware update?

The LED needs to blink red when you connect the V6. Otherwise, it won't be recognised.

The RF60 should be recognised as is, though. However, make sure to remove the batteries first.

Sorry if you are doing all of the above already. My best bet is that you haven't successfully circumvented the Win 10 protection against non-signed drivers. Note that you have to go through the procedure Antonio pointed to after every restart of your computer. The drivers won't stick, so to speak and you have to convince Win 10 that you really want to install the drivers all over again.
